    摘要： An audio decoder decodes a bit stream of encoded audio data, wherein the bit stream of encoded audio data represents a sequence of audio sample values and comprises a plurality of frames, wherein each frame includes associated encoded audio sample values. The audio decoder comprises a determiner configured to determine whether a frame of the encoded audio data is a special frame comprising encoded audio sample values associated with the special frame and additional information, wherein the additional information comprise encoded audio sample values of a number of frames preceding the special frame, wherein the encoded audio sample values of the preceding frames are encoded using the same codec configuration as the special frame, wherein the number of preceding frames is sufficient to initialize the decoder to be in a position to decode the audio sample values associated with the special frame if the special frame is the first frame upon start-up of the decoder. The decoder comprises an initializer configured to initialize the decoder, wherein initializing the decoder comprises decoding the encoded audio sample values included in the additional information before decoding the encoded audio sample values associated with the special frame.

    摘要： The invention relates to a method for determining a sequence of values for a coding parameter of a hybrid coding scheme for every frame of a frame sequence for use in the coding of the frame sequence by means of the hybrid coding scheme. The hybrid coding scheme allows to determine resulting distortions and compression rates for the frames of the frame sequence if the frame sequence is completely coded and if a genuine partial sequence of the frame sequence is incompletely coded, in such a manner that a genuine subset of the set of distortions and compression rates such as they can be obtained by coding using possible sequences of predetermined values for the coding parameter for every frame. Estimated distortions and compression rates for frames of the frame sequence are determined (202) and the sequence of values for the coding parameter of the hybrid coding scheme is determined based on the resulting and estimated distortions and compression rates previously determined.
